Ducted propeller

A ducted propeller, also known as a shrouded propeller, features a cylindrical housing or duct that surrounds the blades. This design improves efficiency by directing and accelerating water flow, reducing turbulence and noise. The duct also provides added protection to the blades from debris and impacts. Commonly used in boats and underwater vehicles, ducted propellers enhance performance, stability, and safety, especially in confined or challenging environments. They are an effective solution for improving propulsion while minimizing environmental impact and operational risks.
